One way collision on tilemaps

[BenClarkson]

Hey, I am hard at work on my game "Space Cat" and I have some questions about one way collision on tilemaps. Like, is there a way to do this without making the one way colliding tiles into immovable objects (which I assume isn't TERRIBLE, it still uses the quadtree but it has to update more variables).

I have a collision tilemap in two layers, one with "ground" and "walls" and one for one way platforms. The problem is how the tilemap body is handled isn't super clear.

I was thinking of writing an extension of the collide function to specifically deal with this. 

Any help would be groovy.

Not sure on this one but this seems to suggest you can set collisions per-face: http://docs.phaser.io/Phaser.Tile.html#setCollision

yup!

 

tile.collideLeft = false;tile.collideRight = false;tile.collideUp = true;tile.collideDown = false;tile.faceUp = true;tile.faceDown = false;tile.faceLeft = false;tile.faceRight = false;

yup!

tile.collideLeft = false;tile.collideRight = false;tile.collideUp = true;tile.collideDown = false;tile.faceUp = true;tile.faceDown = false;tile.faceLeft = false;tile.faceRight = false; 

 

I am curious to know if there is any difference/preference between this and setCollision? http://docs.phaser.io/Phaser.Tile.html#setCollision

Currently I'm having problems getting collideDown to work at all.

No, setCollision is just a convenience method:

    setCollision: function (left, right, up, down) {        this.collideLeft = left;        this.collideRight = right;        this.collideUp = up;        this.collideDown = down;    },
